Among the order Hymenoptera, parasitoids are the group with the greatest species richness, so much so that emphasized that their diversity is so great that the need for basic collections has preceded ecological observations. The objective of this study was to report the species of parasitoid immature stages of Diptera obtained using pitfall traps and metal container traps in Brasil. The dipterous pupae were obtained by the flotation method. They were individually placed in gelatin capsules until the emergence of the parasitoid. Parasitoids collected in the trap ptifall 220 and 183 in metal container. The trap pitfall Gnathopleura quadridentata Wharton (Hymenoptera: Braconidae) was more frequent specie with 71.3% in the metal container Pachycrepoideus vindemmiae (Rondani) (Hymenoptera: Pteromalidae) was more frequent with 55.6%. The attraction of the traps in relation to specimens of parasitoids and the species of parasitoids were not statistically significant. Key words: natural enemy, biological control, State of Goiás
